TELEPHONE-DESK STAN DAHD.

SPECIFICATION forming part of Letters Patent No. 770,157, dated September 13, 1904.

Application filed August 9, 1902.

1'0 alt w/Lmn it may concern:

Be it known that I, CHARLES L. BOYCE, a citizen of the United Statesiresiding at Detroit, in the county of Wayne and State of Michigan, have invented a certain new and useful Improvement inTelephone-Desk Standards, (Case No. 1,) of which the following is a full, clear, concise, and exact description.

My invention relates to a telephone-desk standard, and has for its object to provide an improved and simplified structure which may be easily and quickly assembled and in which the switch mechanism and circuit connections will be thoroughly protected when the device is in use, while easily accessible for the purposes of inspection, repair, or adjustment when necessary.

I will describe my invention by reference to the accompanying drawings, and the features or combinations which I regard as novel will be pointed out in the appended claims.

Figure l is a view in elevation of my improved desk-standard. Fig. 2 is a plan view thereof. Fig. 3 is a vertical sectional view. Fig. 4 is a similar view showing the switch mechanism in an alternative position. Fig. 5 is a vertical sectional view in a plane at right angles to the plane of Figs. 3 and 4:, showing how the switch mechanism and telephone-support may be removed as a unit from the standard or casing.

The same letters of reference designate the same parts wherever they are shown.

The stem or casing a is simply a cylindrical metal tube or hollow column mounted upon a suitable base-plate a, and the switch mechanism with the binding-screws, &c., for electrical connections are mounted upon a frameplate 6, which also carries the transmittersupport 6 and is contained within said casing. The frame-plate Z) is provided with a circular cap 6 adapted to fit the mouth of the tubular casing a, and in assembling said frame-plate is simply inserted in the tube until the cap Z2 rests in place at the mouth thereof, as shown, and a screw 0 is then passed through from the outside of the easing into a lug 5 carried by Serial No. 118,979. (No model.)

the frame-plate, whereby the same is securely held in place. The telephone switch-lever d, which is forked, as shown, to support the telephone-receiver in a Well-known manner, is pivoted at CZ, to the frame-plate 6 near the cap and projects through a slot or opening a in the tubular casing to near the mouth thereof. Said switch-lever is of the bell-crank type, and the downwardly-extending arm (Z thereof is arranged to actuate the switch-springs e0 which are anchored at their lower ends upon an insulating-blockf, fixed transversely upon the frame-plate b, said springs extending longitudinally of the frame-plate and carrying insulating-studs and platinum contact-points to be engaged by the switch-arm (Z as shown. A spring a is mounted upon the frame-plate 6 and is adapted when the receiver is removed from the switch-hook d to move said hook or switch-lever and cause the arm (Z thereof to bring the switch mechanism into the position illustrated in Fig. 3, the contact-springs e c i being both in contact with the metallic switchlever (Z and so electrically connected, and the spring 0 being held out of engagement with said switch-lever by the insulating-stud a carried by said. spring. When the telephonereceiver is placed on the hook, its weight overcomes the tension of spring 6 and the parts assume the positions shown in Fig. 4, the spring 6 being in contact with the lever-arm C12 and the springs c 6 being held away from said lever-arm by the insulating-studs e a which are carried by springs e 6', respectively. The connecting-wires may be led through an insulating-tube a into the hollow base a and thence to the removable frame-plate 5, passing through holes 6* in said frame-plate to the binding-screws or points of attachment for said wires. In assembling, the wires may be fastened in place upon the frame-plate 6 before the same is inserted in the casing, after which the wires would be passed into the mouth of the casing and out at the bottom through the tube a and the frame then fitted into the casing, as before described.

It will be appreciated that the whole switch mechanism and the transmitter-support may be removed as a unit from the rest of the standard upon simply removing the screw 0.

Having thus described my invention, 1 claim as new, and desire to secure by Letters Patent, the following:

1. In a telephone-desk standard, the combination with the tubular casing a, of the frameplate 6 removably supported longitudinally therein, said plate having a cap adapted to fit the mouth of said casing and carrying a transmitter-support above said cap, switch-springs mounted upon the lower portion of the frameplate and extending upward along said plate, and a bell-crank switch-lever pivoted to said frame-plate, one arm of said switch-lever projeetingthrough an opening in the casing and being adapted to support the receiving-tele- "be removed as a unit from the hollow standard, as set forth.

In witness whereof I hereunto subscribe my name this 11th day of July, A. D. 1902.

CHARLES L. BOYCE.
